DF Direct Weekly #59: PlayStation 5 VRR, Steam Deck 40-60Hz Upgrade, 900W Next-Gen GPUs?
Playstation 5 finally gets their VRR update but as you watch the video on their experience on it, you realize how good and innovative G-sync was back in 2013 even compared to modern VRR implementations.
PS5 follows HDMI 2.1 VRR spec for it's system wide implementation which is 48hz+ while Xbox does slightly more which is 40hz+. The issue is that if a game goes below 48hz on PS5, VRR gets disabled on PS5. So you have this situation where with Elden Ring, it goes in and out of VRR range so while the experience is improved, it's still not ideal. Now both the PS5 and Xbox have their own solutions to this. On PS5, game devs will need to specifically optimize their games to go below the 48hz VRR range. VRR on PS5 also doesn't work on any PS4 games. On Xbox, you can set your output to 120hz mode and the VRR minimum VRR range goes down to like 20hz but it can have persistence blur in some games so not ideal unless you really need it.
Meanwhile G-sync in 2013: 1hz-Max refresh rate system wide... (While the module itself can go down to 1hz, typically the LCD monitors can't go below 30).
Truly the definition of "It just works"

AMD publishes VCN4 (Video Codec Next) patches for RDNA3 GPUs, no AV1 encoding support so far
That's actually kinda bad. Even Apple's M1 supports AV1 encoding. We will see if Nvidia's Lovelace will or not.
Nvidia's A100 vs AMD's MI250 benchmarks
Finally some MI250 vs A100 benchmarks coming out of ECP. NekRS. A100 crushes Crusher with some weird numbers on the FDM kernel "The initial implementation sustained up to 5 TFLOPS (FP32) on the A100, but less than 3 TFLOPS on the MI250X (and even worse for even-order expansions)" pic.twitter.com/JUqCK5rGB0
